March 02, 2025

Geoduck (Panopea generosa) is a large, long-lived burrowing clam native to the Pacific coast of North America and especially associated with the Pacific Northwest. Its long siphon, crisp texture, and mild sweet-briny flavor make it one of the region’s most recognizable shellfish.

This is the main Global Seafoods geoduck hub. Use it for an overview, then follow the focused guides for cooking, recipes, nutrition, harvesting, aquaculture, sustainability, sushi, and regional cuisines.

Taste and Texture

The siphon is firm and crisp when sliced thinly, while the body is softer. Prolonged cooking can make the siphon tough, so many cooked preparations use brief heat.

Cleaning and Cooking

A common preparation method is to briefly blanch the geoduck so the outer siphon skin can be removed more easily, then clean and cut the meat according to the intended dish. See How to Cook Geoduck and Geoduck Recipes.

Raw Geoduck and Food Safety

Geoduck is served raw in some cuisines, but raw shellfish is not risk-free. Public-health agencies warn about hazards including Vibrio, while marine biotoxins are managed through harvest-area monitoring and closures. Approved commercial sourcing and proper cold handling are important, but freshness alone does not eliminate raw-shellfish risk. People at higher risk of severe foodborne illness should avoid raw or undercooked shellfish.

Wild Fishery and Aquaculture

Washington has both a commercial wild geoduck fishery and geoduck aquaculture. These are separate production systems and should not be described as interchangeable. Read Geoduck Sustainability, Geoduck Farming in Washington, and How Wild Geoduck Is Harvested.

Buying Geoduck

For live geoduck, source and handling matter. Buy from a reputable commercial seafood supplier that maintains the cold chain and appropriate shellfish traceability. For current availability, shipping information, and ordering, visit the Global Seafoods Live Geoduck product page.

A brief blanch to loosen the siphon skin is a preparation step, not full cooking. Cook raw seafood thoroughly; the general temperature recommendation is 145°F. Raw preparations carry additional risks.
